Debating Teacher Pay

David Z. Hambrick of Michigan State University concludes his piece with an appeal to common sense:

As a society, we have decided that it’s fine to pay a heart surgeon more than an electrician. We didn’t need to run a regression analysis to decide this — it’s important to keep the lights on, but only if there’s someone to keep them on for — and we don’t need to run a regression analysis to decide that we don’t pay teachers enough. A little arithmetic will do. In Michigan, where I live, the average starting salary for a teacher is about $35,000 for nine months. That works out to about $20 an hour. A bartender can make double that. Which job do you think is more important?
